“Better” doesn’t matter; evolution has no goals. If there was a random mutation that caused the shell to be numb *and* that change made it more likely for that one specific turtle to survive when others would’ve died, then that would have been passed along to its children. So either that random mutation has never happened, or it happened but didn’t particularly help with survival.

probably because if they couldnt feel pain on their shell they would be in more danger of being killed. if u had no nerve endings in ur skin, as a human, then what is stopping u from getting into a bath with scorching hot water and burning it all off. disturbing image i know but pain/general feeling of touch helps organisms avoid danger

The point of the shell is to provide physical protection, which it does by being hard. It would actually be very dangerous for the turtle to have no sensation on its shell because then it wouldn’t be able to tell if the shell was being breached or damaged.

Well you assume “feel” is the same everywhere.
It’s like you still feel on your knee caps and the heel of your foot. But they are significantly better at delivering blunt force than lets say, your shoulder or head. Done parts of the body can just take more without being painful.

You can use your fingernails to tap on a desk, it’s kinda the same thing: you can ‘feel’ through your fingernails and it’s different from skin and it doesn’t hurt as much but if there’s massive damage then it’ll hurt.
